For the first time, polymer scientists from the University of Massachusetts Amherst have discovered the factors that control the final size and shape of chiral filament bundles that self-assemble into different architectures. The research team, which included Greg Grason, Isaac Bruss and Douglas Hall, along with Justin Barone from Virginia Tech, reported the experimental results that support their novel model. The study has been reported in the current issue of the Nature Materials journal.
The Department of Energy’s (DOE) Oak Ridge National Laboratory (ORNL) has developed a new processing technique for two-dimensional (2D) electronic devices. This new technique has the potential to reduce the power consumption of the devices, and to increase their efficiency and mechanical flexibility.
Heterostructures (referred to as Van der Waals {VdW}) are attracting a great deal of attention due to their diverse physical and chemical properties. A VdW heterostructure is assembled by stacking two or more different 2D semiconducting crystals on top of each other.
Arthritis and sport-related injuries are a common occurrence in the elderly, athletes and others who experience severe pain as a result of damaged cartilage tissues. Scientists have now demonstrated how to use 3-D bioprinting to create cartilage tissues that could resolve this issue.
A solid’s surface usually melts into a thin liquid layer prior to the melting point. This phenomenon of surface melting occurs in all categories of solids: for example, two ice cubes can fuse at a temperature less than 0°C as the premelted surface water is surrounded inside the bulk at the point of contact and is frozen. Premelting promotes crystal growth, and is vital in geology, metallurgy, and meteorology, such as frost heave, snowflake growth, glacier movement, and skating. As there is a lack of microscopic measurements, the causes of several premelting scenarios and the impact of dimensionality on the premelting phenomenon are poorly understood.
Scientists have successfully integrated hypothetical calculations and sophisticated in-situ microscopy to reveal critical clues about the properties of an advanced energy storage material for use in batteries and supercapacitors. The study was conducted by researchers from Oak Ridge National Laboratory (ORNL) of the Department of Energy (DOE).
Researchers from Aix Marseille Université, based in Marseille, France, have devised a method that enables real-time and in-situ monitoring of physical processes that take place at materials’ surfaces at the atomic level.
A breakthrough method, developed by a team of researchers headed by the City College of New York chemist Mahesh K. Lakshman, reduces the barrier that inhibits the easy formation of new molecules. The novel technique facilitates the generation of new molecules by cleaving typically inert bonds.
Scientists from the University of Amsterdam (UvA) and the Hong Kong University of Science and Technology (HKUST) have achieved single-particle resolution, for the first time, in the investigation of surface premelting phenomena.
Carbodeon has developed a new additive for fluoropolymer coatings, based on its uDiamond® NanoDiamond technology.
